Voltage drop in diode

  1. Nov 20, 2009 #1
    the depletion region is resposible for voltage drop
    all that is fine
    but in forward bias there is no depletion region hence there can be no voltage drop
    but it is mentioned in my book that the voltage will drop by .7 volt
    how come this can happen

    also i have many doubts in transistor amplifiers
    waiting for reply's
